我們一般安裝第三方包（pulp）會通過cmd命令： conda install pulp

　　但是今天安裝pulp包的時候出現下面的問題：

C:\Users\81584>conda install pulp
Fetching package metadata .............

PackageNotFoundError: Packages missing in current channels:

- pulp

We have searched for the packages in the following channels:

- https://repo.continuum.io/pkgs/main/win-64
- https://repo.continuum.io/pkgs/main/noarch

　　一開始我沒找到解決方法，上網查閱之後可以按照以下方法進行：

　　（1）、執行 anaconda search -t conda pulp

　　　出現如下東西：

C:\Users\81584>anaconda search -t conda pulp
